<p>An interaction between Google Analytics and Django's cookie parsing could allow
an attacker to set arbitrary cookies leading to a bypass of CSRF protection.</p>
<p>The parser for <code class="docutils literal notranslate"><span class="pre">request.COOKIES</span></code> is simplified to better match the behavior
of browsers and to mitigate this attack. <code class="docutils literal notranslate"><span class="pre">request.COOKIES</span></code> may now contain
cookies that are invalid according to <span class="target" id="index-0"></span><a class="rfc reference external" href="https://tools.ietf.org/html/rfc6265.html"><strong>RFC 6265</strong></a> but are possible to set via
<code class="docutils literal notranslate"><span class="pre">document.cookie</span></code>.</p>
